Summary
This study examined 1222 biological specimens for acid-fast bacilli (AFB), finding an 11.29% infection rate. Men showed a higher infection rate than women, with pus and sputum being the most common positive specimen types.
Area of Science:
- Microbiology
- Infectious Diseases
- Clinical Diagnostics
Background:
- Acid-fast bacilli (AFB) are a group of bacteria that can cause serious infections.
- Early detection of AFB is crucial for effective treatment and disease control.
Purpose of the Study:
- To determine the prevalence of acid-fast bacilli (AFB) in various biological specimens.
- To analyze the infection rates in relation to patient demographics and specimen types.
Main Methods:
- A total of 1222 biological specimens (sputum, pus, urine, biological liquids, biopsies) were collected between October 1991 and December 1995.
- Smears were prepared, treated, and stained using the Ziehl-Neelson method for AFB detection.
- Microscopic examination was performed to identify positive cases.
Main Results:
- Out of 1222 specimens, 138 (11.29%) tested positive for AFB.
- The infection rate was higher in men (7.53%) compared to women (3.76%).
- Pus specimens showed the highest positivity rate (19.44%), followed by sputum (12.30%). Sputum constituted the majority of specimens examined (84.45%).
Conclusions:
- The study highlights a significant prevalence of AFB in the examined population, with notable differences between genders.
- Pus and sputum are key specimen types for AFB detection, emphasizing their importance in diagnostic strategies.
- Findings underscore the need for continued surveillance and targeted diagnostic approaches for AFB infections.
